![]() I add up the wattage of my equipment x the number of hours each set is on per day and multiply by 30. Then I multiply that by the $/kwh.
My systems are mainly low power, with the exceptions being 3 x 250w MH on for 10 hours/day. I also have 4 Sedra 9000 pumps going 24/7 (2 skimmer @ 55w/2 returns @ 90w) and those are my main draws. Low power lighting over the fowlr, seahorse, goldfish, sump & shrimp tanks & med. power (4 x 55w PC) over the planted community. The HOB & cannister filters, powerheads & such draw very little & I keep my tank temps on the low side with no ill effects. Until a couple days ago, didn't even have a heater plugged into the reef tank & the fish/corals were fine in the low-mid 70s. On my other tanks, I estimate the heaters to be on 12 hours/day or less. In the winter, my bill rises due to heaters but not huge. I made sure I went with slow flow for the returns so less power needed (some friends use 300w return pumps for instance). My wife's goldfish tank probably draws 50 watts max/hour with lights for 8 hours & 30w for the other 16 hours daily. I use a clip on light with a 27 watt Phillips Daylight CFL bulb over my sump & 2 over my seahorse tank. (in other words, a Tek HOT5 is way over kill for a sump light) The 210g reef draws approx. 315 watts 24/7 (pump, powerheads, skimmer, fuge light, 80w UV) and 1065 watts for 10 hours when the MH lights come on. At $.065/kwh (old rate), that's $.69 for 10 hrs & then $.29 for the other 14 hours. That's roughly a dollar for the reef or $30/month for my reef tank. All the other tanks' equipment combined do not equal what my reef tank draws. My rough calculations is $1/day for the other 5 tanks. Actually, with those 2 new tanks I added since I last did this calculation, I guess I'm up to $60/month for powering this addiction. Averages out to $10/tank since I have 6 different tanks running. Not bad. I know it's too late (you've already bought and installed your equipment) but there are low power alternatives to many things needed for the tanks. I went from a 250w MH pendant over my seahorse tank to 2 x 27w clip on CFL lights. I harvest and sell my macro every week or two, so they work fine for nutrient export. I have smaller heaters (150w to 200w) and keep my tank temps in the low to mid 70s without any issues. It sounds like you have your sump in the basement & so you need a high power pump to send water up 10+ feet to the display tank, whereas I can get away with a 90w Sedra. Anthony

![]() Ask my friends. She made me tear down a 6'6" planted community discus tank over a 6' rainbow/congo tetra tank, then tells me she wants a fancy goldfish tank as I'm draining my tanks of water.

![]() a while back i bought a power meter from costco kinda like a kill-a-watt meter and i found other than the lights heaters where my biggest problem with 4or5 tanks usually running i had about 1000w of heaters which were costing me between $1-2 per day my 8 bulb tek light which is around 400w was costing me about $0.75 per day other things where seio powerheads and some things around the house, with all my tanks i average about $250 a month, usually one is a bit lower for the estimate and 1 is a bit higher and i calculate power at $0.11
some things actually use alot less power than they say or i would expect so that was a nice change,mh lights on the other hand use up to 20% more than they say so 750w of halides is probably over 1000w and costing you up to $2 per day also about the heaters, i found it much cheeper to run my heat up all day and night then to have the heaters sucking up power i think anyone with a bigger reef or multiple tanks should buy a meter, i got mine from costco online for $35 and ive seen canadian tire selling them in the flyers for about the same, kill-a-watt meters are about $50 but i think they have some better functions

![]() My old tank with dual 400 halides, 320 watts of T5, 150 watts over fuge, return pump, powerheads, skimmer, ect. only cost $50 a month.
I really don't see how your bill can go up that much just from the tank! |
